About Promptfoo
Promptfoo tracks every new frontier model while its scanning action sheds an old runtime.
The main line's rhythm is provider coverage — Claude Opus 5, Kimi K3, GPT-5.6, Grok 4.5 and current Azure and Gemini models all landed within a few releases, alongside websocket URL templating and a steady stream of assertion and red-team fixes. The newest entry is not the evaluator itself but its code-scan GitHub Action, which drops Node.js 20 as a breaking change and hardens its supply chain.
